' Application filed June 16, 1913'. Serial N o. 774,009.

Patented Sept. 22, 1914.

To all whom it may concern;

I Be it .known that I, IRA B. MALABY, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented .certain Improvements in 'Wall-Anchors, of

Figure 1 is a side elevation of'one form.

of my invention; Fig. 2 is a plan of the wall anchor shown in Fig. 1; Fig. 3 is aplan of the blank from which the body of the wall anchor is made Figs. 4 and 5 are side elevations, partly in section, illustrating my invention in position ready for expansion, and in the form assumed after expansion, respectively;.Fig. 6 is an elevation of a modified form of my invention, and Fig. 7 is an elevation partly in section illustrating a special form of my invention applied to support an eyebolt.

Referring to the above drawings, 1 represents the blank of which the wall anchor compri'sing my invention is preferably formed; this being made of a body of sheet metal, usually steel, of the requisite thickness and so formed as to have a series of elongated projections or fingers 2, extending from one of its edges. The blank is also provided with a number of transversely elongated holes 3 in its body portion, and by suitable machinery is rolled up into an approximately cylindrical form so that the fingers 2 project at one end. A nut 4' of suitable dimensions ismountedso as to be encircled by said fingers, being put in place either before the blank is rolled up or after this operation, and said fingers may there- 1 although after bebent inwardly as indicated at 5, so as to support the nut some distance away from the body portion of the blank. They may also be turned over at their ends as indicated at 6, to prevent the removal of the nut, if desired the latter may be seated upon t e end of the body portion as shown in Fig. 6, with its corners projecting between the various fingers 2, which in this case may be provided with an integral strip 7 joinmg their outer ends so as to holdthe nut in place.

In using such a wall'anchor as shown in either Figs. 1 or 7,, there is first formed a substantially cylindrical hole 8 in the wall or other structure 9 in which the wall anchor is inserted. After mounting'a jam nut 11 and a washer 12 on a bolt 10, the threaded end of the latter is entered in the nut 4, and after-said bolt has been screwed partly or wholly through this nut, it is held firmly and immovably in place. Thereafter the bolt 10 may be removed merely by unscrewing it from engagement with the nut 4 and a bolt having threads of the proper pitch may be screwed into the socket provided by this wall anchor so as to support any desired :sFtructure such as the angle iron 17 shown in If desired, the washer 12 and jam nut. 11 may be mounted on a bolt which is to permanently remain in engagement with the wall anchor, and said bolt, as shown in Fig.

7, may be itself used as the expanding tool. In this case, the eye bolt 18, after being entered in the nut 4, may be held from turning by .a suitable bar and thereafter the jam 'nut ll'may be turned up so as to cause the structurally weak side members 14 to be bulged outwardly into holding engagement or other structure 9.

I claim 1. The combination in a wall anchor of a body of sheet metal in substantially cy-v lindrical form, having apertures in its sides with the walls of the cavity 8 in the masonry .and projeeting'fingers at one end, with a nut embraced and immovably held by said fingers, the corners of the nut entering the spaces between the fingers and the latter being bent over at least one face of said nut.

2. The combination in a Wall anchor of a" b dy f sheet-metal in su tantiall ylind ivfingers and mounted with its corners procal form, having apertures in its sides and projecting fingers at one end; with a nut embraced and immovably held by said fi11-' gers; there being portions of the fingers extending over the nut to hold it in place.

3. An expansible wall anchor consisting of a tubular body having elongated aperturesin its sides, forming structurally Weak side members, and a series of fingers projectin from one end; with a nut inclosed by sai jecting between the same; said nut being seated on theadjacent end of the body portion and 'having parts of the fingers extending over it. I

4'. The combination in a wall anchor of a tubular body portion of sheet metal having elongated side openings providing structura1ly wjeak side members; a series of fingers projecting from one end of the body portion and having their outer ends connected together to provide a series of openings; with a nut embraced by said fingers and having its corners projecting in said openings.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
